Injecting watermark into a picture

The project consists in the implementation of two procedures, i.e., inject()and extract() that inject and extract an arbitrary large bit string (watermark) [Copy Right by CSC] into a picture using the LSB technique Requirements: Usage of object oriented programming The code should be commented Usage of two methods, i.e., inject and extract Management of exceptions, i.e., too large watermark. Different injection strategies (to be chosen by the user) (i) sequentia injection, (ii) random spreading, (iii) mark repetition Possibility to choose the number of mark replicas A method detect that detects the mark length using a statistical approach such as auto correlation. Implementation of a technique to recover the watermark from a corrupted image Implementation of a technique that prevents mark detection.
